As the demand for storage space increases we have seen a handful of manufacturers releasing larger and faster USB 3.0 pen drives. In January we reviewed the Kingston DataTraveler HyperX Predator 512GB drive which broke new ground for performance. The only downside was the asking price, a staggering £650 inc vat. Today we are looking at the latest SuperSonic Magnum 256GB USB 3.0 pen drive, priced at a more palatable £250 inc vat.
